TRIO/KENWOOD KA-9X INTEGRATED AMPLIFIER SIGMA DRIVE

TRIO/KENWOOD KA-9X STEREO INTEGRATED AMPLIFIER
I found in Google that in order to use the Sigma Drive, you need to connect a thicker wire for the main terminals and thinner wire for the Sigma Drive Terminals. I just used copper speaker wire available in my place and connect it properly to attain the high damping factor of this amplifier. The speaker I used is the Polk Audio Tsi 200. Thank you.

Thanks for showing how to connect second set of wires. I can not beleive that in this way has 1000 damping factor.

[@aqmgameshobbies8165]

Yes it says 1000 damping factor. I also read other vintage kenwood's that has 2000.

It's nice to see a sigma drive system in action. I'd be curious to know your honest opinion about this amplifier...

[@aqmgameshobbies8165]

As for the sigma drive, I really dont know if there is difference since I am just an average music lover. For the amp, Im very happy with the purchased. Its powerful, does not get hot compared to my other amp Lo-D. It even drive easily my 83dB RS33TB Pioneer Speaker. Thanks
